UFC 148: Silva vs. Sonnen II is an upcoming mixed martial arts (MMA) pay-per-view event promoted by the Ultimate Fighting Championship (UFC) on July 7, 2012. The card will feature six televised MMA bouts on pay-per-view, as well as five preliminary bouts. It is the seventeenth UFC event of the year and will take place at the MGM Grand Garden Arena in Las Vegas. The card's main event features the UFC Middleweight Champion Anderson Silva defending the title against Chael Sonnen. The co-main event is a rubber matchbetween Forrest Griffin and Tito Ortiz.
Since a win over Nate Marquardt in early 2010, Sonnen has been a polarizing figure due to his unrelenting criticism of Silva and trash talk, including comments directed towards Silva's manager, teammates, coaches, wife, and home country of Brazil. Silva had remained relatively quiet until a UFC 148 media call in June of 2012, in which he stated through a translator: "Chael Sonnen's going to get his ass kicked like he's never gotten his ass kicked before. What I'm going to do inside the Octagon is something that's going to change the image of the sport. This is going to be violent and I am sorry. I'm going to make sure that every one of his teeth are broken, that his arms are broken and his legs are broken. He's not going to be able to walk out of the Octagon by himself. I can guarantee that. He will need a plastic surgeon afterwards. And I know that he’s listening, so the game’s over. No more shit talking. It’s on now." This caught many by surprise, as these remarks were perceived as out of character.
